Guys, how can a girl get you to text back?

Okay so I have read that guys like to handle one thing at a time. Meaning if you’re busy with work, or if you are busy with school, or doing something else, if a girl messages you “Hey :-) How are you?” You aren’t going to want to reply because you don’t feel like getting into a long conversation with her at the moment. But let’s say it’s been 4 days since you have texted the girl. You guys are REALLY into each other, but you haven’t texted her. This could be because you’re simply to busy to have a conversation or something like that. I have read though that if a girl sends you a sexy picture or sexy message, you’ll respond to that because, well, that definitely peaks your interest. I have also read that if something dramatic happens in her day, and she sends you a message about this drama, like “My dog died today and I am very sad about it and my step dad yelled at me for dropping a spoon and my friend Emily told me she hates me.” then you are less likely to respond to that right away, if you even respond to that at all. I have also read that a message like “Hey you :-) Hope your day’s going well! Thinking about you and missing you. Love you ;*” makes you smile and feel happy because it doesn’t really require reply, it was sweet, short, simple, and straight to the point. Now lets say you’re with this girl. You love her, she loves you. You last talked to her 4 days ago. She missed you so she sent you the short message above 2 days ago. You haven’t responded, but you have read it. How can this girl get you to reply to her? Should she send you a sexy message? This girl loves sexting with you but also hopes for a meaningful conversation as well. So, what can this girl do/say to make you message her back right away because you genuinely really want to.
